Dear sir or madam,
I have been developing C++, C# projects successfully since 6 years ago.
I have long experience for development of controlling, G-code generation softwares of CNC machines and 3D printers.
I have worked on similar projects to what you are looking for, and I am confident I can exceed your expectations.
I will respect and implement your needs from day one, so that you are going to be satisfied with the delivered work.
A short chat-check won't cost you but can bring us together to success.
Kind regards
PS: If you want the example, I can send my sample video.
